Liquid Over Water!!!

Problem Scenario

Some people might want to know how fast ice melts in different liquids so that they will know about how long it will take to melt. You might need to know how long it take for like a recipe or something like that where you have to melt the ice and you might want to know how long it takes to do that. I decided to do this project because it is something I have wanted to know science I was little because I would put ice in my water and come back a little bit later and the ice would be gone. So I figured I would do a project to show how long it takes to do it. Also I figured I would do it in different liquids because I figured some of them would melt in different times because it must have chemicals and stuff in it and that would make it melt faster or slower so oi did that and got my results.

Broad Question

How Fast Does Ice Melt?

Specific Question

Do Different Types of Liquids Affect Melting of Ice?

Hypothesis

If you use cold soda then it might melt faster because of all the sugar and carbonation in it. If you use water it might melt faster too because of the way that ice melts in water anyway.

Graph of Hypothesis

Variables

Independent Variable: Liquid
Dependent Variable: Melting Time

Variables That Need To Be Controlled: Size of cup, amount of liquids, amount of ice, and size of ice.

General Plan

I am going to be doing my experiment at home at the kitchen table because my experiment doesn't take that much time to do so I don't think it will really bother people if it is not going to take much time so I will just do it at home.

Potential Problems And Solutions

I will actually be measuring the liquids by using a measuring cup so it will all be the same amount of liquid in the cup. Im going to be timing how long it takes to met the ice in it. So that is going to be how i am going to do everything.

Safety Or Environmental Concerns

A concern that i have is that someone will drink it because there is a lot of people in my house but i will just put a sign or something to get them to not touch it.

Experimental Design

(add the correct headings from the experimental design page before beginning)

Resources and Budget Table

Item	Number needed	Where I will get this	Cost
Ice cubes	3	I have it at home	0
Cups	3	I have it at home	0
Juice	1 cup	I have it at home	0
Soda	1 cup	I have it at home	0
Water	1 cup	I have it at home	0

Detailed Procedure.

1. Gather all of the items together such as soda, juice, water, four cups, and stopwatches
2. Pour 1 cup of soda in one cup, 1 cup of juice into the next cup, 1 cup of warm water in another cup, and 1 cup of cold water in the last cup.
3. Take a tray of ice cubes out
4. Put one ice cube in each of the cups
5. Start the stopwatch
6. Put the times of each liquid on a piece of paper
7.Then do whatever u want with the liquids when they are done
8.Then put it on the wiki page

Data Analysis

All Raw Data

Some data that was collected during the project was what the ice looked like. The ice was at one point rounded. In the beginning the ice was like a rough oval shape..kind of like the bottom of your foot at one point it rounds in on the side and that is exactly what it looked like it rounded in on the side.

Results

The results that I got were that the hot water had melted first. When you look at my background research it shows that things will melt faster when you have it a little warmer because of the ice being cold and the liquid being warm. Then after that melted the cold water melted and I figured that was going to happen because warm water melted first so then I thought oh you know the warm water melted so I am guessing the cold water would melt after. After the cold water melted the soda melted. I thought that was going to melt first because of the chemicals and all the sugar but then doing the research I found out that water was probably going to melt first and soda would probably come after that. The last thing that melted was the juice. I never really found out why that melted last or why it took so long because it took like 30 to 45 minutes to melt in the juice.

Conclusion

As a result for my project the data shows that the hot water melted the ice first. I think that the hot water melted the ice because the water is hot and the ice is cold so that would obviously melt the hot water first. Then after that the cold water melted the ice. I think that melted the ice because when u put an ice cube under cold water it melts pretty fast so I thought that was going to happen. Then the soda melted next I thought that was going to melt first but then I realized that the water was going to melt first because of how water melts under water itself...I thought that the soda was going to melt first because of all the sugar and chemicals in it but it didn't it melted 3rd. The last was juice.I used apple juice and it took a long time to melt.. I don't know why because I thought that it was going to go faster because it doesnt have as many chemicals as like soda and stuff.

Discussion

My experiment went just as planned. Well my hypothesis was wrong but everything else went right. My hypothesis was that the soda was going to melt first because of all the chemicals then the water then the juice but that didn't happen. What happened was that the hot water went first the cold water went second the soda went third and the juice went last. So i was right about the juice but nothing else. The good thing is that I was able to find the answer to my question and my variables went together. The thing that I could of done better with my experiment is that I could of done it more than two times just to see if everything was right because they were a couple seconds off so I just used the first data table that I made. Also I could of made it so that when I did the experiment it went better because at one point I had to time the other cups of liquid but when I had to stop the stopwatch the other ones continued melting so I didn't get the right thing until i found out i should do two stopwatches. One for getting the time when they have to stop and the other for timing the other cup when i am getting the time for the cup that has already melted.

Benefit to Community and/or Science

This benefits the community because some people may want to know How fast Ice melts in different liquids. When people have things like buffets and have to know when the ice melts in different liquids and how fast it melts and stuff they could like use that information and make a solution or something. That may sound wild but some people want to know how fast it melts in liquid because when you put ice in liquids it makes it more watery and then it taste different because it is watered down and some people don't like when that happens. Also now if u work at a restaurant you will now know what liquid takes the longest to melt ice and you might want to serve people that.

Background Research

As you suspect, the melting rate of an ice cube in a liquid depends partially on the liquid's density as well as its heat capacity. One would expect an ice cube to melt more quickly in a warm, dense liquid with high heat capacity as the liquid would be able to transfer more of its heat more rapidly to the ice cube, thus melting it. In beverages that are chilled, we are dealing with a complex thermal equilibrium process in which the surroundings first need to heat the chilled liquid which, in turn, needs to heat the ice cube. If the beverage is chilled, a denser liquid with a higher heat capacity would actually preserve the ice cube longer because the surroundings won't be able to warm up the dense liquid as quickly as they would be able to warm up a similar but less dense liquid. The question becomes more complicated when dealing with liquids other than water because we have to start considering solvation effects. Different liquids will be able to dissolve solid water with varying degrees of efficiency depending on their molecular structure. Generally speaking, liquids that can dissolve water very efficiently will melt the ice more rapidly while liquids that cannot dissolve water very efficiently will take longer to do so given that everything else remains the same. It is difficult, overall, to make generalizations based on this information because density, heat capacity, and salvation capability all affect one another in solution and complicate their effects on the ice cube.

Abstract

Do different types of liquids affect melting time? How fast does ice melt? Well that what my project is all about! My project was to take three different types of liquids and time how fast it takes to melt. It took about 30 to 45 minutes in all to melt all of the ice in each of the cups. I didn't think it was going to take that long. My hypothesis was that the water would melt after the soda would melt and that the juice would melt last. My hypothesis was wrong. What happened was that the hot water had melted first then the cold water then the soda and last melted was the juice. I never quite figured out why the ice melted last in the juice but when I was doing my background research it said that ice melted faster in warm water because the water is hot and it would melt something cold faster because it is hot against cold. So that is why the water melted first. The cold water melted after and that melted second because is is water against water and also because the cold water is a little warmer than the ice and water is a dense liquid so that would be why it would melt faster. The soda went after the water and i never figured out why that melted second either. Other than that my project went as planned and everything went like it should of gone.
